Abstract: A hermetic compressor is provided, comprising: a cylindrical shell; a stator fixed to inner surface of the shell; a rotor rotatably installed with respect to the stator; a compression unit combined with the rotor to be rotated together with the rotor; a stationary shaft including an eccentric portion around which the compression unit is supported stationary with respect to a longitudinal direction thereof; an accumulator fixed to inside of the shell in such a manner sealing the upper end of the shell and fixedly supporting one end of the stationary shaft above the stator; a lower frame fixed to inside of the shell and fixedly supporting the other end of the stationary shaft; an upper cap to seal the upper end of the accumulator; and a lower cap to seal the lower end of the shell.

Abstract: A compressor is provided having an accumulator that forms an accumulating chamber in an internal space of a shell of the compressor, reducing a size of the compressor and simplifying an assembly process. A stationary shaft having a refrigerant suction passage may be directly connected to the accumulator to prevent leakage of refrigerant. Further, a center of gravity of the accumulator may correspond to a center of gravity of the compressor to reduce vibration and noise of the compressor caused by the accumulator. Furthermore, an eccentric portion may be provided at the stationary shaft to secure a spacious compression space. Both ends of the stationary shaft may be supported by a frame to reduce vibration. Also, a rotor and a cylinder may be coupled with a bearing in an integrated manner to reduce cylinder deformation. An installation area of the compressor including the accumulator may be minimized to enhance design flexibility of an outdoor device employing the compressor and minimize interference with other components, thereby facilitating installation of the outdoor device.

Abstract translation: 提供一种压缩机，其具有蓄压器，该蓄压器在压缩机壳体的内部空间中形成蓄压室，从而减小压缩机的尺寸并简化组装过程。 具有制冷剂吸入通道的静止轴可直接连接到储液器以防止制冷剂泄漏。 此外，蓄能器的重心可对应于压缩机的重心以减少由蓄能器引起的压缩机的振动和噪音。 此外，可以在固定轴处设置偏心部分以确保宽敞的压缩空间。 固定轴的两端可以由框架支撑以减少振动。 而且，转子和气缸可以与轴承以一体方式连接以减少气缸变形。 包括蓄能器的压缩机的安装区域可以最小化，以提高采用压缩机的室外装置的设计灵活性并且使与其他部件的干扰最小化，由此便于室外装置的安装。
